So Joy's entire problem with Danny is he didn't tell her about her father?
Um correct me if i'm wrong but didn't The Hand say Joy would be killed if she was told about her father being alive? Yeah Danny's such a piece of shit that he deserves to be mutilated and tortured for trying to keep Joy safe. I mean its not like Danny just kept him being alive a secret for the hell of it, he was literally doing it to keep her fucking safe.
Her motivation for revenge against Danny just seemed dumb and the poorest bit of writing from an otherwise good season. I understand her anger with Ward i guess, but Danny didn't deserve any of it.
Joy seemed to ignore the fact that her father was a psychotic abusive monster, its kind of a good thing you was kept away from him and not told he was alive.
